Transverse myelitis in antiphospholipid antibody negative systemic lupus erythematosus.

Acute transverse myelitis is a well known neurological complication occurring in systemic lupus erythematosus. Many prior studies have shown a link between transverse myelitis and the presence of antiphospholipid antibodies. Earlier theories have linked thrombotic tendency to be the culprit in such manifestations but currently there is evidence to support other causative mechanisms.
